<p>Highlighters can be used to provide visual emphasis to an element; during user interactions for example.</p>

<p>In the above demo, we listen to the paper for the <code>cell:pointerclick</code> event, then highlight the cell that was clicked.</p>

<pre><code>paper.on('cell:pointerclick', function(cellView) {
    cellView.highlight();
});</code></pre>

<p>As you can see it is possible to highlight a cell as follows:</p>
<pre><code>cellView.highlight();</code></pre>

<p>Unhighlighting a cell is simple too:</p>
<pre><code>cellView.unhighlight();</code></pre>

<p>To highlight a cell using a specific highlighter (and options):</p>
<pre><code>cellView.highlight(null/* defaults to cellView.el */, {
    highlighter: {
        name: 'stroke',
        options: {
            width: 3
        }
    }
});</code></pre>

<p>Or you can specify just the highlighter's name (its default options will be used):</p>
<pre><code>cellView.highlight(null/* defaults to cellView.el */, {
    highlighter: 'stroke'
});</code></pre>
